Not your drive, not your data.
Isn't this like saying "not your house, not your possessions" ? But landlords cannot just take or misplace my stuff, especially if I pay rent and have some rights.
They sure can. Years ago I had a shitty landlord clear an apartment I'd moved 95% of my belongings from but before the term of my lease had ended. Now you may have some legal recourse, but the cost/time associated with litigating a matter like that tends to outweigh the remedy.
